To all whom. itmay concern:

Beit known that-1, KAESTEN KNUDSEN, a citizen. of the United ,Statenresiding at Chi. cago, in the county ofCook andsState of Illinoie, haveinvented a certainnew and useful Improvement in Electric VehiclesLof`which the following is a full, clear, concise, and exact description,reference being had to the accompanying drawings, forming a part of thisspeciiicetion. l

My invention relates to au electric vehicle, my object being toprovide-a novel driving?v gear between the motell and the posltively.'driven o r propelling'wheels of the vehicle.

I have illustrated my invention in the ac- -companying drawings, 'inwhichX Figure lis a plan view illustrating 'the ve'- Fig. 2 is a. viewin elevation thereof. Fig. 3 is a front view of the frame. Fig. 4 is adetail view illustrating the -A mounting of one ofthe guidingwheels.Fi'g.

is a. similar viewas seen from above.y Fig. 6 is a' cross-sectional viewo'n line `6 6, Fig. 4.

Fig. 7 is a. view in section of the motor 4and transmitting-gear. Fig'.8 isa view of the motor in elevation. Fig. 9 isan end view of thediderential driving-gear. Fig. 10 is a sec-A Like letters refel to like'parts in the several igu res.

Upon the rear axle a are mounted brackets qa' a', havingupwardly-extending arms a2 as,

l .carrying sleeves a a5 upon'the ends, through x which pass thelongitudinal rods or tubes b b.

VThe tubes b b are joined by a transverse tube b', from-which aresupported vertical rods b2,

Coled springs cl c* rest between said To the opposite end of themotor-frame'are secured brackets cs c3 journaled u on the rear axle a.

' The tubes b b, are joined at the forward ends by a pair of transversetubes d d', which pass through the sleeves d d, carried upon theupperends o'f arms l4 d", providedon a center piece or bracket d.Between the 'arms d4 d is a web carryina 'seatd7 for the spring da.

The center piece d is bifurcated, and between the :members thereof is acenter piece d,

pivoted upon journal-piu d. Upon the sides of the center piece d aremounted brackets d9 d, each carrying two sleeves d10 d1, placed side byside, within which are secured the 5 5 ends of the tubes e e', theopposite ends. of which aresecured in sleeves egcs, carried upon thebrackets e, havin bifurcated ends, between the members e of which arejour- 'naled the transverse portions f of'the axles. L6o f -upon whichthe front wheels are journaled.

As illustrated more clearly in Figs. 4. and 5,

the hub g of the wheelis provided with a.prjecting barrel joxrnaled uponball-bearings. upon the axle, f', bile the journal rests with- 6 5 in ahollow space in the hub, the journal-pin e? occupying a verticalpositionl in the plane ofthe `wheel and directly-above the tread of -thewheel.. An 'operating-arm 7"z is secured.

to the transverse portion f, whereby the axle 7o maybe rocked -upon-itspivot to change'the position of the wheell in guiding the same. Asshow-n in Fig. 1f, the arns'f are joined byf .t a transverse-rod f",which may-be connected with the guiding-lever in any usual manner.' 75Upon the lower lend of thecentral bracket d is provided an arni J,carrying a sleeve di, in which fit the ends of the bracing-tubes h 72,the opposite ends 'of which lit in sleeves e e', carried-on the brackete.

Thearin'ature 'of the motor is mounted upon 'a hollow shaft k, withinwhich .is -journaled a shaft 1c', carrying at one end a pinion k2 and atthe opposite end a bevel-gear la, meshing with piniouslc4 k, journaledupon the-interior 8 5 of a box orcasingk, mounted upon the hol-4 I .lowshaft k, The pinions k* k mesh with the 'bevelgear las, Amounted juponthe shaft le?,

which forms a. continuationA of shaft 7c. Upon the end of shaft 7ciscarried apiniou ks. As 9o shown in Fig. 1;the pinions k2 lo mesh withgear-wheels `Z Z', mounted, respectively, upon the\hubs of the wheels mm', the hubs of these wheels being journaled uponthe rear axle byball-bearings. As the armature of the motor 95 rotates the hollowshaft kis rotated,- carrying with it the casing k, upon `which the pinions lo?lo are journa-1e`d. When the vehicle is .traveling'in a straightllii1e,.the pinions 7c* k do notrotate about their own,axes,and theirroo bodly'movementsprod. "e aki'otation of the shafts kf k', due to theinterlocking of the mitting motion` tothe rear ordriving wheels.,

- which the-rotating element thereof is mountl In turning a curve, whereone of the wheels musttravel faster thanthe other, the 1piii'ions,

while serving to rotate the shafts kk are rotated upon their own axessufficiently to accommodate theduiffereuce in the speed of ro'- tationof the shafts k it?, respectively.

I reserve the feature of pivotal mounting for the guiding-wheels for a.divisional application. Having described my invention, what I claim asnew, and desire to secure by Letters 1. In 'an electric vehiclethecombination w ith an electric motor, of a'hollow shaft upon which therotating element thereof is mounted, a pair of shafts journaled withinsaid h'ol- -low shaft and geared respectively with the opposite wheelsof the vehicle, bevel-gears mounted on the opposed ends of said shafts,a pair of pinions engaging therewith and mounted ou the frame or casingsecured to and rotating with said hollow shaft, substau.

tiallyas described.

2. In an electric vehicle, the combination with an electric motor of ahollow shaft 'on ed, a pair of shafts journaled therein, a pinionmounted upon the outer end lof each of saidshafts, a pair ofvehicle-wheels each carrying a gear-wheel meshing with one of saidpinions, a pair of\bevel-gears mounted upon the opposed ends of saidshafts, a pairof pinframef or casing,'secured to fand .rotating withysaid hollow shaft, substantially as described.

3. Avehicle-frame comprising a rear axle, upwardly-extendingbracketsmounted there'- ,on, a pair of longitudinal tubes secured in saidbrackets, a cross-piece, an electric-motor frame journaled to the rearaxle and resiliently suspended from said crosspiece, a cross-piecejoining said longitudinal tubes at the forward end of the frame, acenter bracket upon which said` cross-piece is supported, tubesextending laterally from said center piece each carrying brackets upon`th'e ends, and a pair of axles mounted uponsaidbrackets to rotateabout vertical axes, substantially as described.

In witness whereof I have hereunto slibl scribed my name in the presenceof two wit- .DBBBS.
